Application filed ApriliB, 1912. Serial No. 694,162.

To all whom it may concern.'

Be it known that we, JOSEPH CLoNTz and ALFRED BRETz, citizens of theKingdomsof Roumania and of Austria, respectively, residing atYoungstown, in the'county of Mahoning and State of Ohio, have inventedcertain new and useful Improvements in Cold-Air Machines, of which thefollowing is a specification.

The present invention relates to certain new and useful improvements inthe design and construction of air cooling and moistening machines suchare adapted to be employed in connection with buildings and likestructures for vent-ilating purposes.

The object of the invention is to provide a machine of this characterwhich Is com- V paratively simple and inexpensive in its construction,which can be easily operated, and which will serve in an effectivemanner to moisten and cool the air passing through the same.

With these and other objects in view, the

invention consists in certain novel combinations and arrangements of theparts as will more fully appear as the description proceeds, the novelfeatures thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which Figure 1 is aperspective view of a cold air machine constructed in accordance withthe invention. Fig. 2 is a horizontal sectional view through the same..Fig. 3 is a vertical longitudinal sectional View through the same. Fig.4 is a transverse vertical sectionalview through the rear end of themachine, looking toward the forward end thereof, and Fig. 5 is a detailview of the spraying nozzle and stationary disk.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Specifically describing the present embodiment of the invention, thenumeral l designates a casing which is of an elongated formation, and isprovided at the rear end thereof with suitable air inlet openings 2. Theforward end of the casing is tapered, as indicated at la, and providedat the extreme end thereof with an outlet opening 3 through which thetreated air discharges into the room or compartment. n

A cold water pipe 4 enters the casing through the rear end thereof andhas the Inner end' extended downwardly at 5 toward the bottom of thecasing. A spraying nozzle 6 is applied to the lower extremity of thecold water pipe, and a stationary disk or plate 7 is arrangedimmediately under-thefnozzle 6, the said plate being shown as supportedin anelevated position above the floor of the casing by means of asuitable standard 8. T'he cold water fiowing through the pipe 4 isdischarged through the nozzle ,6 in a spray which strikes against thestationary disk 7 and is broken up thereby into minute particles whichare adapted kto permeate the entire rear end of the casing.

A transverse shaft 9 is arranged within the rear end of the casing 1,one end of the shaft projecting through the casing to the exterior whereit is provided with a drive wheel `10, the said wheel being shownk ashaving a handle l1 applied thereto. This shaft 9 is provided with a gearwheel 12 which meshes wit-h a pinion 13 on a countershaft 14 which alsoextends transversely across the interior of the casing 1, and has theends thereof suit-ably journaled upon the side walls of the casing.Paddles or beaters 15 are applied to opposite ends of the shaft 14, thesaid paddles being adapted to be rotated through the medium of the drivewheels 10 so as to act as beaters and cause ya thorough mixing of theair and spray.

At a point between the beaters 15, the shaft 14 is provided with abeveled gear wheel 16 which meshes with a beveled pinion 17 at the rearend of a longitudinal shaft 18. This shaft 18 is journaled in a bearing19 at the upper end of a standard 20 and in a bearing 21 upon a crossbar 22, the forward end of the shaft being provided with a suction fan23. This suction fan 23 is driven simultaneously with the beaters 15 andserves to cause the air to circulate through the casing and bedischarged through the outlet 3 at the forward end of the casing. Itwill thus be obvious that the cold water is discharged from the nozzle 6in a spray which strikes upon the stationary disk 17 and is broken up bythe same into a fine mist which permeates the entire rear end of thecasing. The rapid rotation vof the paddles or beaters 15 causes a.thorough mixing of the spray with the air so as to cool and moisten theair, while a continuous circulation of air through the casing is causedby the fan 23. The top of the casing may be provided with a pair ofdoors 24 which normally close the casing, but which can be readilyopened at any time to ad mit of access being had to the interior of thecasing.

Having thus described the invention, what we claim as new and desire tosecure by Letters Patent, is zl. A machine of the class describedcomprising a casing having an air inlet at one end and a dischargingopening at its opposite end for the moistened and cooled air, awater-spray producing device arranged within the casing, rotary beatersarranged within the casing in advance of the said water-spray producingdevice, a circulationproducing fan arranged beyond the beaters, andcommon driving means for the beaters and the said fan.

2. A cold air machine including a casing through which air is adaptedtopass, water spraying means at the rear end of the casf ing, a transversedrive shaft extending across the casing and having one end thereofprojecting through the easing, a drive wheel upon the proj ecting end ofthe shaft, a second transverse shaft extending across the casing andgeared to the drive shaft, a pair of rotary `through which air isadapted beaters upon opposite ends of the second shaft, a longitudinalshaft arranged in the casing and geared to the second shaft, and acirculation producing fan upon the longitudinal shaft.

3. 'A cold air machine including a casing to pass, an inverted 'waterspraying nozzle arranged within the rear end of the casing, a stationaryplate under the water spraying nozzle for breaking up the sprayed waterinto a inist, a transverse drive shaft extending across the casing,means for turning the drive shaft, a second transverse shaft extendingacross the casing and geared to the drive shaft, a pair of rotarybeaters on opposite ends ofthe second transverse shaft, a longitudinalshaft having one end thereof geared to the second transverse shaftbetween the rotary beaters, and a circulation producing fan upon thelongitudinal shaft.

In testimony whereof, we hereunto affix our signatures in the presenceof two witnesses.
